No, they are more expensive than standard pads, if mine were anything to go by at 25,000 miles when I sold the car the pads were only about 1/3rd worn. So the whole package is better.
There is one further thing to be cautious of, the cars come equipped with extended wheel bolt shafts because they can be easily chipped and ruined by careless handling so tyre replacement needs to be left to a very responsible set up. Obviously you fit one once the standard wheel bolt has been removed.
This also opens up my favourite pet hate about Porsche car salesman, when my friend was specifying his new Caymen the salesman said 'are you likely to want to track your car', he said yes and was told he should have Carbon Ceramics. At which point I mentioned that if by any chance you left the track and hit the kitty litter/small stones trackside you could completely ruin your discs which is a fact.
Most of the die-hard track guys I met with 911 track weapons all changed their Carbon Ceramics for steel discs for this reason alone.
The other big plus point is absolutely no brake dust so if you have fancy silver coloured wheels they stay clean.
